Problems solved by technology

At present, mainstream smoke collection devices are often only effective for certain types of compounds or within a specified volatility range. A single trap cannot collect all cigarette smoke, and the collection efficiency is low. Usually, it is necessary to connect different absorbers. device to absorb various components in cigarette smoke
[0003] In smoke analysis, cigarettes are usually sucked with a rotary smoking machine, and the Cambridge filter is the main tool to capture harmful substances and aroma components in the mainstream smoke of cigarettes. There are often some deviations in the analysis of the full components of cigarette mainstream smoke
